TUCSON, Ariz. — Left turn collisions are the leading cause of crashes in intersections in Tucson, according to data from the Tucson Police Department.
TPD Capt. Diana Duffy looked at the number of left turn crashes in intersections from Aug. 2018 to Sept. 2019. Data showed 197 crashes happened within 10 major intersections.
According to the data, the top five intersections for crashes are near, or above two crashes per month.
The Tucson City Council, TPD, and the Tucson Department of Transportation are working together to implement more protected left turns.

Council member Steve Kozachik says adopting more protected left signals will reduce the number of crashes significantly.
"What we're talking about is putting a lag left," Kozachik said. "And it's after all the other movements have stopped. That's automobiles, it's bikes, it's pedestrians. So that the only thing happening in the intersection is the person making a left turn."
TDOT recently implemented flashing yellow turn signals at intersections along Speedway. That change has helped reduce the number of crashes, according to spokesperson Mike Graham.
The City is looking into what intersections to add protected left turns, and when they could be installed.
